I'm trying to ID what appears to be a a Wittnauer watch that belonged to my great uncle. In the batch of miscellaneous watches there was another Longines labeled as a Datomatic that I'm not convinced is real so I didn't bother posting to the forum for help, but this watch seem legit.
It has a solid case back and does not appear to work. Hands move freely, but watch does not wind. The case back is stamped with what appears to be an identifying mark below the lugs and notes that it is 10k gold filled. The crystal is some sort of hesalite (pictures are below). There is a slight indention on the opposite side of the case from the crown; I assume this is where the case separates.
Thanks for any input you might have!
